Project Summary/Abstract Gymnastics is a leading cause of head injury among sports- and recreation-related activities and is the second most common cause of emergency room visits for non-fatal traumatic brain injury among non-contact sports. Despite this, return to play protocols in gymnastics have scarcely been researched. As a sport, gymnastics is composed of six disciplines: men’s artistic, women’s artistic, rhythmic, acrobatic, trampoline and tumbling, and aerobic gymnastics that utilize various skills showcasing balance, power, and artistry. Women’s artistic gymnastics is the most popular discipline of gymnastics and has been recommended for developing strength and coordination in female youth athletes. However, the physical demands of the sport often lead to a variety of injuries, including concussion, and females disproportionately represent a higher percentage of gymnastics- related injuries treated in hospitals. Athletes recovering from concussion are reintegrated back into sport using a guided return to play protocol. Existing post-concussion return to play protocols developed for contact sports, such as football, may not be relevant to acrobatic sports and are not grounded in biomechanical evidence informing the unique exposure profile of gymnasts. With ~ 5 million Americans participating in gymnastics-related activities, there is a critical need to understand the complex loading environment of the head in gymnastics to inform return to play protocols in the sport. The objective of this study is to characterize kinematics of the head across women’s artistic gymnastics skills for the development of a biomechanically-informed post-concussion return to play protocol in the sport. In Aim 1, 11 beginner-level (age 11-13) and 11 advanced-level (age 13-15) gymnasts will be fitted with mouthpiece-based head motion sensors. Biomechanical data will be collected and quantified during all practices to determine the frequency and magnitude of head accelerations experienced during normal participation of the sport. A sub-sample of athletes will complete a series of skills with two progressive safety modifications, to evaluate the effect of safety modifications on reducing head acceleration. In Aim 2, mixed methods will be used to integrate return to play guidelines identified from literature and data from Aim 1. Stakeholders will be engaged to develop and refine a biomechanically-informed post-concussion return to play protocol in women’s artistic gymnastics. Outcomes will include characteristics of the protocol and dissemination materials for national organizations to consider for adoption. This R03 small pilot study seeks to change the paradigm in which concussions are managed in gymnastics and will result in methods and key data to support a large-scale study evaluating the effectiveness of the return to play protocol on reducing symptomatic episodes and recovery time following concussion while assessing optimal implementation strategies in this environment. This approach will provide a framework that may be expanded to other disciplines of gymnastics and acrobatic sports to improve the safety of over 5 million athletes participating in acrobatic activities.

项目概要/摘要 体操是体育和娱乐相关活动中头部受伤的主要原因，也是第二大原因 非接触性运动中非致命性脑外伤导致急诊就诊的最常见原因。 尽管如此，体操作为一项运动，重返比赛的方案却很少被研究。 分为男子艺术、女子艺术、节奏、杂技、蹦床、翻滚六个项目， 有氧体操，利用各种技巧展示女性的平衡性、力量和艺术性。 体操是体操中最受欢迎的项目，被推荐用于发展力量 然而，这项运动对身体的要求往往会导致各种变化。 包括脑震荡在内的伤害，以及女性在体操运动中所占的比例过高—— 在医院治疗的相关损伤的运动员通过使用重新回到运动中。 为接触性运动制定的现有脑震荡后重返比赛指导方案， 例如足球，可能与杂技运动无关，并且没有生物力学证据 了解体操运动员的独特暴露概况 约有 500 万美国人参加与体操相关的运动。 活动中，迫切需要了解体操中头部的复杂负载环境，以 为这项运动的重返比赛方案提供信息。这项研究的目的是表征头部的运动学特征。 跨越女子艺术体操技能，以发展脑震荡后的生物力学知识 重返这项运动的比赛规则 在目标 1 中，11 个初级级别（11-13 岁）和 11 个高级级别（13-15 岁）。 体操运动员将配备基于咬嘴的头部运动传感器，并收集生物力学数据。 在所有练习过程中进行量化，以确定所经历的头部加速度的频率和幅度 在正常参与这项运动期间，运动员的子样本将由两名运动员完成一系列技能。 渐进式安全修改，以评估安全修改对降低头部加速度的影响。 目标 2，将使用混合方法整合从文献和数据中确定的重返比赛指南 目标 1. 利益相关者将参与开发和完善基于生物力学的脑震荡后恢复 女子艺术体操比赛的结果将包括比赛的特点和内容。 供国家组织考虑采用的传播材料。这项 R03 小型试点研究旨在： 改变体操中处理脑震荡的范式，并将产生方法和关键数据 支持一项大规模研究，评估重返赛场协议在减少症状方面的有效性 最佳脑震荡后的发作和恢复时间，同时评估此实施策略 这种方法将提供一个可以扩展到体操其他学科的框架。 和杂技运动，提高超过500万运动员参加杂技活动的安全。
